Two students were given a physics problem for finding maximum extension of spring if blocks are imparted velocities `v_(1)` & `V_(2)` when spring is unstrected. By Students A: `1/2m(v_(1)+v_(2))^(2)=1/2kx^(2)` By Students B: `1/2mv_(1)^(2)+1/2mv_(2)^(2)=1/2kx^(2)`A. Student A is correct, Student B is wrongB. Student B is correct, Student A is wrongC. both are correctD. both are wrong |
